HYDRO CARBON MOTOR.

Specification of Letters Iiatent.

Patented Mar. 7,

To all whom it may concern:

Be it known that I, Jnssn G. VINCENT, a, citizen of the United States, and resident of Detroit, Wayne County, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon Motors, of which the following is a specification.

This invention relates to hydrocarbon motors.

The objects of the invention are to provide means whereby the motor and the parts associated therewith, such as the body, frame or Cowling, of a land or air motor vehicle are protected from fire, to enable gravity feed to be used from the fuel supply tank to the carburetor and to provide a construction whereby in the conduction of the explosive mixture from the carburetor to the cylinders an exchange of heat is effected between the mixture conduit and the interior of the crank case so as to heat the mixture and cool the lubricant, and the invention also aims to provide an embodiment of features accomplishing the above objects which is particularly adaptable to V-type motors. 4

With these objects and others in View, the

invention is embodied in preferable form in the arrangement and construction hereinafter described and illustrated in the accom panying drawings, in which:

Figure 1 is a side View partly broken away of a motor embodying the invention; and

Figure 2 is an end view partly in vertical section.

Referring to the drawings, 14 indicates the cylinders in one of the rows of a V-type motor and 15 indicates the cylinders in the other row. -1o is the crank case. Below the crank case and substantially aligned with the vertical central line of the motor is mounted a carburetor 17. This carburetor has two outlet branches 18 and 19 which communicate with conduits 20 and 21 which lead upwardly through the crank case on opposite sides of the center line of the case, and

projecting intake header 24. An intake header is provided for each row of cylinders and is adapted to extend transversely of the cylinders in such row along the inner sides of the cvlinders within the valley formed by the V between the two rows, and each header is provided with means of communication with tne various cylinders in the row correspond 111g thereto.

The carburetor is provided with intake pipe which is straight and vertical and extends for a substantial distance below the carburetor and which has its lower end open to the atmosphere. By this construe tion, any fuel that may fall back from the manifold conduits or from the carburetor will drop into the air passage and thence escape to the atmosphere, thus preventin the collection of fuel in the passage of th e carburetor or on parts of the supporting and enclosing structure adjacent thereto. A 0 should any back fire occur the flame wil be blown out through this vertical downwardly passageway away from the eng1ne. The intake pipe is adapted to be projected through the cowling within which the motor is mounted, a section of such part being indicated at 25. This projection of" the pipe through the bottom of the body surrounding the motor makes certain the protection of such body and the vehicle from fire. Such arrangement is, of course, particularly applicable to and useful in connection with airplanes, since it serves to carry all back fire that may occur entirely outside of the fuselage of the plane Owing to he relatively low level at which the ('arburctpr is mounted with respect to the motor and the supporting parts therefor, it is rendered possible to employ gravity feed of the fuel which is also an advantage of particular importance in connection with the use of a motor in airplanes.

As the mixture is led through the conduits 21 and 22, it will be heated by the heat of the oil in the crank case suiliciently to avoid the necessity for having an auxiliary heating system for the mixture. At the same time the carburetted air passing through the conduits serves to cool the oil in the crank case.

The location of the carburetor below the motor also increases the accessibility of the various operating parts of the motor by leaving the valley and sides of the motor a n air free from the-obstruction usually offered by the carburetor as ordinarily located.

Having thus described my invention, what I elaimis:

'1. In combination with a hydrocarbon motor having two rows of cylinders, an intake header for the cylinders in each row. consisting at a hollow mixture receiving body adjacent'said cylinders, a common carburetor for said rows of cylinders below the motor, a crank case,.conduits leading from said carburetor throirgh the crank case, a pipe leading from one crank case conduit to one of said headers, and a pipe leading from the other conduit to the other header,

and means of communication between each header and the cylinders of a row.

2. Thecombination with a hydrocarbon motor having two rows of cylinders, of a crankcase upon which said cylinders are mounted, said crankcase having conduits,

open at the bottom of the crankcase and extending upwardly therethrough, a carburetor connected to the crankcase at the lower ends of said conduits, and piping leading from the upper ends of said conduits to the motor cylinders.

In testimony whereof I affix my signature.
